Buckwheat hulls (or sobakawa) make an ideal pillow filling as they hold their shape extremely well and do not compress and flatten, so your neck is properly supported throughout the night and your body is kept properly aligned.
No one likes to wake up in the middle of the night to flip their pillow around due to a sweaty head. The 3d shape of buckwheat hulls allow for air circulation so you can sleep cool all night long.
ComfySleep pillows are filled with Ecocert certified organically grown buckwheat hulls from Canada. They are sieved and cleaned with forced air to remove all fragments and dust. They are not roasted, fumigated or treated in any way so you can sleep easy knowing that no pesticides or harmful chemicals were used to grow or clean the hulls used in our pillows.
